[Create an audience](https://developers.google.com/data-manager/api/devguides/audiences/google-ads/customer-match/create-audience) and note the value of its [`id`](https://developers.google.com/data-manager/api/reference/rest/v1/accountTypes.accounts.userLists) field, or use [`userLists.list`](https://developers.google.com/data-manager/api/reference/rest/v1/accountTypes.accounts.userLists/list) to retrieve the `id` of an existing Customer Match audience. 2. [Upload members to the audience](https://developers.google.com/data-manager/api/devguides/audiences/google-ads/customer-match/upload-data) by passing the audience `id` as the `productDestinationId` in an [`audienceMembers.ingest`](https://developers.google.com/data-manager/api/reference/rest/v1/audienceMembers/ingest) request. 3. [Check upload results and list size](https://developers.google.com/data-manager/api/devguides/audiences/google-ads/customer-match/check-results) using request diagnostics and the `sizeInfo` field on the audience. 4. [Remove all members from an audience](https://developers.google.com/data-manager/api/devguides/audiences/google-ads/customer-match/remove-all-members) if you need to replace or clear an existing audience.
